Embodiment Construction
[0014] The invention provides a method for judging interference of relay adjacent nodes based on Hata open fading model. The core idea is based on the Hata open fading model. When the destination node enters the space spherical range centered on the relay node, calculate the signal fading amount and arrival power of the direct communication from the source node to the destination node, and then calculate the relay node to The signal fading amount and arrival power of the destination node, and use the arrival power to calculate the signal-to-interference ratio of the destination node. When the signal-to-interference ratio is less than the threshold, it is determined that the destination node has suffered direct interference from the source node, so that the system as a whole has no effect on the source node or The transmit power of the relay node is adjusted to reduce the interference to the destination node.
